1 US Army Corps of Engineers BUILDING STRONG ® GeoPackage: US Army Geospatial Center April 11, 2012 An Initiative for Standardized Geospatial Formats Optimized for Mobile

2 BUILDING STRONG ® What is GeoPackage? A single container for the storage and use of vector, raster, and tiled caches. Available for use on a variety of mobile platforms. Described by a manifest. Defined by an open standard, free of license.

3 BUILDING STRONG ® Introductions Kevin Mullane – U.S. Army Corps of Engineers, U.S. Army Geospatial Center (AGC) Paul Daisey – Image Matters LLC, Contract Support to the AGC

4 BUILDING STRONG ® Purpose and Motivation Purpose: To introduce the GeoPackage concept to the open source community. Motivation: GeoPackage responds to the need among government and non-government organizations to maintain situational awareness when constrained by limited or non-existent power or bandwidth. Involvement of the broader community is sought so as to converge on an open solution.

5 BUILDING STRONG ® Today Effective coordinated large scale collaboration in military, homeland security, and disaster management relies upon the sharing of geospatial information. An explosion of map applications for mobile handheld devices has resulted in a variety of incompatible data formats and interfaces. No existing standard simplifies the provisioning of all types of geospatial data on assorted makes of mobile handheld devices.

6 BUILDING STRONG ® Objectives Enable the distribution of packaged tile caches, raster, vector and descriptive data in an immediately useable form. Realize capability from existing off-the-shelf solutions including commercial and open source software. Engage developer community through appropriate forums to arrive at non-proprietary solution.

7 BUILDING STRONG ® Initial Use Case: Fixed Product Distribution Geospatial information is collected, processed, analyzed, exploited, and packaged as data products in enterprise server environments Distribution of the geospatial foundation by networked server or removable media Products shareable throughout organizational levels and among all participants GeoPackage stored once per platform to support multiple applications

8 BUILDING STRONG ® Additional Potential: Local Data Collection Collection of observations Sharing of collected observations Geospatially Enabled Analytics Geocoding/reverse geocoding, Mobility analysis, Visibility analysis, and much more

9 BUILDING STRONG ® Initial GeoPackage Requirements Manifest Single self-describing file container to facilitate management and distribution Tile Cache JPEG and PNG Tiles Multiple Tile Matrices Vector Simple Geographic Features Support direct access and update by apps

10 BUILDING STRONG ® Subsequent GeoPackage Requirements Raster Support raw raster formats for visualization and analysis Elevation Data Coverages Routes Web Services for creation, management and distribution Potential Manifest Extensions? Metadata OGC Web Services (WMS, WMC, WFS, WCS) Other Web Services (OpenStreetMap) What else?

11 BUILDING STRONG ® GeoPackage Web Service CONOPS

12 BUILDING STRONG ® Current Plan Identify, prototype, test and specify mechanisms for mobile geospatial data storage, transfer and use to meet identified requirements Base the solution on existing consensus standards, other open specifications and existing technologies; dont (re)invent unless absolutely necessary Do this through an open public collaborative process involving key stakeholders in both the development and user communities Demonstrate interoperability between key stakeholders Gain approval of a consensus GeoPackage specification Achieve widespread commercial and open-source GeoPackage implementation In a one-year time frame

13 BUILDING STRONG ® Standards / Technologies Base ISO/IEC 9075:1992 Information Technology - Database Language SQL OGC r4 OpenGIS® Implementation Standard for Geographic information - Simple feature access - Part 1: Common architecture Version: OGC r4 OpenGIS® Implementation Standard for Geographic information - Simple feature access - Part 2: SQL option Version: Portable Network Graphics ITU-T Recommendation T.81 (09/92) with Corrigendum (JPEG) OGC r9 OGC Web Services Common Standard Version: (Manifest) https://www.gaia-gis.it/fossil/libspatialite/index https://github.com/mapbox/mbtiles-spec

14 BUILDING STRONG ® Summary GeoPackage will meet a recognized need. An open specification is in the best interest of the community. Collaboration is believed to be the most effective way forward. Your participation is encouraged and welcome.
